[Claims for Utility Model Registration] A pump, a pair of actuators that are actuated in the same direction by pressurized liquid discharged from the pump and rotate a steering wheel, and the actuating direction of the pair of actuators is controlled by the direction of the steering wheel. a first direction control valve that switches depending on the steering angle; and a second direction that cuts off the supply of pressure liquid to either one of the actuators when the liquid pressure in the actuator is less than a predetermined value in the hydraulic circuit of the power steering device. A hydraulic circuit for a power steering device characterized by being provided with a control valve.
